Cov xim uas taug kev deb tshaj plaws yog carotene xanthophyll vim nws yog cov dej feem ntau yaj hauv cov kuab tshuaj. Chlorophyll b taug kev tsawg kawg vim nws yog qhov tsawg tshaj plaws nyob rau hauv cov kuab tshuaj.
Hauv qhov no, cov xim twg mus nrawm tshaj plaws?
xim carotene
Tsis tas li ntawd, vim li cas Xanthophyll taug kev deb tshaj plaws? Tsiaj txhu tsim tsis tau xanthophylls , thiab yog li ntawd xanthophylls pom nyob rau hauv cov tsiaj (xws li nyob rau hauv lub qhov muag) los ntawm lawv cov khoom noj. Xanthophylls yog oxidized derivatives ntawm carotene. Lawv muaj pawg hydroxyl thiab muaj ntau dua polar; yog li ntawd, lawv yog cov pigments uas yuav taug kev deb tshaj plaws hauv ntawv chromatography.
Tsis tas li ntawd, cov xim twg yuav taug kev deb tshaj plaws ntawm daim ntawv chromatography?
Carotene txav mus deb tshaj plaws vim tias nws yog qhov tsis zoo tshaj plaws ntawm cov pigments thiab nws tau nyiam ntau dua rau cov acetone-ligroin sib tov (theem mobile) dua li ntawm daim ntawv. Qhov no muaj zog, tsis muaj kev sib raug zoo nrog rau theem mobile qhia tias carotene yog cov xim tsis muaj xim tshaj plaws pom nyob hauv cov zaub ntsuab chloroplasts.
Vim li cas qee cov pigments mus ntxiv hauv chromatography?
Qee cov pigments yaj hauv dej yooj yim dua thiab rub nrog dej nyob deb up daim ntawv. Lwm tus nyiam dua rau daim ntawv thiab txav mus qeeb dua. Feem ntau cov lwg me me yuav txav mus nyob deb dua cov loj.

INTERVENTION: Kev tshuaj ntsuam xyuas rau DIC tau xaj rau cov neeg mob uas xav tias mob. MEASUREMENTS THIAB NTAWV XEEB: Prothrombin lub sijhawm (PT), qee lub sijhawm thromboplastin (PTT), cov khoom fibrinogen/fibrin degradation (FDP), thiab fibrinogen tau siv ntau zaus ua DIC kuaj mob
Lub koom haum ntawm cov leeg pob txha los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj plaws yog dab tsi?
Skeletal thiab cardiac nqaij fibers. Npaj cov leeg hauv qab no los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj plaws: nqaij fiber ntau, fascicle, myofibril, filament, nqaij. Npaj cov nqaij mos sib txuas hauv qab no los ntawm qhov tsawg tshaj plaws mus rau qhov loj tshaj: epimysium, perimysium, fascia, endomysium. cov sarcomere
Dab tsi yog qhov kev txiav txim ntawm cov hlab ntsha los ntawm qhov tsawg tshaj plaws mus rau qhov loj?
Cov hlab ntsha loj tshaj plaws yog vena cava qis dua, uas nqa ntshav los ntawm lub cev qis mus rau lub plawv. Lub superior vena cava coj cov ntshav rov qab mus rau lub plawv los ntawm lub cev sab saud. Capillaries yog cov hlab ntsha me tshaj plaws. Lawv txuas cov hlab ntsha me me thiab cov leeg
Cov hlab ntsha twg cov ntshav siab mus txog qhov ntsuas siab tshaj plaws?
Cov hlab ntsha loj tau txais lub siab tshaj plaws ntawm cov ntshav ntws thiab ntau tuab thiab ywj kom haum rau qhov siab. Cov hlab ntsha me, xws li arterioles, muaj cov leeg du uas sib cog lus lossis so kom tswj cov ntshav ntws mus rau qee qhov ntawm lub cev
Dab tsi yog cov tshuaj cholesterol zoo tshaj plaws uas muaj kev phiv tsawg tshaj plaws?
Hauv kev tshuaj xyuas ntawm 135 cov kev tshawb fawb yav dhau los, uas suav nrog ze li ntawm 250,000 tus neeg ua ke, cov kws tshawb fawb pom tias cov tshuaj simvastatin (Zocor) thiab pravastatin (Pravachol) muaj qhov cuam tshuam tsawg tshaj plaws hauv cov tshuaj no
